Three season sunrooms in Adelanto CA - a closed-in room you can use most of the year
Patio or deck sitting empty most of the year? We close it in with glass or screens so it becomes a room you'll use.
Is a three season sunroom right for your house?
Three season sunrooms in Adelanto, CA close in a patio or deck with glass or screens, so you get a sheltered room off the house that you don't have to pay to heat or cool.
Most of our calls come from homeowners with a patio or deck they hardly use, or an older room they'd like to get more out of, and the first choice is whether the room stays unheated or becomes a four season sunroom you heat and cool. The price mostly moves with the size of the room, what it sits on and whether that base needs work, and the glass, screens and doors you pick. The schedule depends on settling those choices before anything is ordered and on the permit paperwork, which we take care of after checking with the city or county office that covers your address. When I come out to measure, we'll go through each one so you get a figure for your own room.
How we build a three season sunroom
Even an unheated room has to be tied firmly into what it sits on, so the first thing I look at is your slab or deck and how the room will connect down to it. Then we talk about heat, because if you think you might want it someday, telling us now lets us plan for it from the start. Once the base, the glass or screens and the doors are settled, we order the room, and our crew ties the frame into the base, sets the roof and wall panels, hangs the doors and cleans up before leaving.
Some homeowners only want an open patio closed in, and a patio enclosure can do that with less building. When the yard slopes, the roofline is awkward or you want a layout no stock room offers, we plan one of our custom sunrooms around your house instead.

The owner measures and plans it
I come out myself to look at the job, measure and talk it through with you, and our own crew, led by a lead installer, does the building. You're working out the room with the person who plans it, so nothing gets lost between the visit and the build.
Building sunrooms since 2017
I started the business in 2017 after years of scheduling crews for a busy building company, where I saw jobs stall because a choice got made too late. That's why we settle heat, insulation, glass and what the room sits on before anything is ordered, since changing those after the walls are up is harder and costs more.
Licensed and fully insured, every job
We're licensed and fully insured, and I'm happy to show you both before you sign. Ask any contractor you're comparing for the same, because the question below about who can build a sunroom explains why it matters.
Designed to county weather values
San Bernardino County publishes wind speed, snow load and rainfall flow values for the communities in the county, so ask us which ones your room's design used and we'll walk you through them. The city's zoning code also sets standards for residential lots, and we check how they apply to where the room will sit on yours.
On a room like this, the base and the heat question decide almost everything else, so those are what we settle first. We're based in Adelanto and take jobs in many of the cities around it, on both sides of the county line, so send us a few details or call (760) 523-8749 and I'll set a time to come out.

Three season sunroom ideas
What people ask about three season sunrooms
What is a three season sunroom?
A three season sunroom, also called an enclosed porch or enclosed patio, is a room off the house that isn't heated or cooled and has uninsulated windows or screens. It gives you a closed-in space without the heating and cooling a four season room carries, which is the main reason people choose it.
How much does a three season sunroom cost in Adelanto?
Across Southern California, a sunroom usually costs about $16,000 to $120,000 per job. Larger rooms that need a foundation and come with heating and air conditioning sit at the high end, so size, the base and heat are what push the price up. I'll give you a figure for your own room after I measure, and every room we build is backed by our satisfaction guarantee.
What is the best way to put a sunroom on an existing deck or patio?
Start by checking whether the deck or slab can carry the room, because an existing base may need reinforcing for the added weight. Every sunroom also needs a continuous load path, an unbroken chain of connections carrying the room's forces down to the foundation, whether it sits on concrete or wood. One sunroom company notes that a wood deck is usually more adaptable and can cost less, concrete is the strongest and most permanent, and posts holding up a frame suit a sloped yard or an existing surface.
Who is allowed to build a sunroom in California?
In practice, a licensed contractor, because the state only lets an unlicensed person take jobs under $1,000 when the work needs no permit and they have no employees. If any permit applies, a license is required even below $1,000, so ask to see your installer's license before you sign.
Can I add heat to a three season sunroom later?
You can, but it often costs more, because highly insulated windows and insulation in the walls, floor and roof are much easier to put in while the room is being built. A room that's fully heated and cooled with all-weather windows is a four season room, so if there's a real chance you'll want that, it's worth weighing both before anything is ordered.
How do I take care of a three season sunroom?
Keep the door and window tracks clean and use pure silicone spray on them instead of an oil-based lubricant, which one maker's care guide says tends to attract dirt. The same guide says to keep the weep holes, the small openings that let water drain out, clear.
